The only animal language we can understand isn't produced by an ape or a dolphin but the honeybee; by carefully interpreting a complex sequence of movements and vibrations called the ‘waggle dance’ we can understand bees telling one another the quality, distance and precise location of a food source.

The waggle language was first decoded by Austrian zoologist Karl von Frisch (1886-1982); each waggle, for example, represents an increment of 50m from the hive for a source of food.

Von Frisch first published his findings in 1945, and was eventually awarded the Nobel Prize in 1973, sharing it with Konrad Lorenz (for his work on imprinting in birds) and Nikolaas Timbergen (aggression in sticklebacks).

It is still the only Nobel Prize ever awarded for the study of animal behaviour.

F. was awarded the Nobel Prize in Physiology or Medicine in 1973 along with two other ethologists Konrad Lorenz and Nicholas Tinbergen "for their discoveries relating to the creation and establishment of individual and group behaviors." "The discoveries made by Nobel laureates this year ... ... may seem not so important in terms of human physiology or medicine - he said in a speech on the occasion of awarding Borge Kronholm at the Karolinska Institute. - However, these findings served as a prerequisite for extensive research, the object of which were also mammals. " Also added Kronholm, the work of laureates can be essential to assess "the impact of abnormal psychosocial situations on individuals", - such actions, he said that "can cause not only a deviation in behavior, but also serious physical illnesses" like hypertensive disease or myocardial infarction. F., who by that time turned 87 years old, represented at the ceremony by his son Otto.

, an Austrian ethologist, studied honeybees and showed that they use dance to communicate food locations to other bees. Von Frisch noticed that when one honeybee found food, others appeared around the food. He then studied the bee’s movements when it found the food. two different movements or dances. A round dance, which tells other bees to search for food close to the hive and a waggle dance which told other bees the direction and distance to fly toward the food. This study on a population of honeybees helped scientists further understand the movement and food searching methods of the bees. Von Frisch mainly used the scientific process of observation and analysis to reach his conclusions on honeybee dances.

Upon completing graduate school, Dr. Wenner began teaching at the University of California in Santa Barbara and continued his research on communication in honey bees. While doing so, he eventually recognized serious discrepancies about assumptions basic to the honey bee dance language hypothesis. By repeating von Frisch’s original experiments with additional controls incorporated into those experiments, he and his co-workers obtained results at variance with results others had obtained when they ran such experiments with lesser controls.

In 1923, ethologist Karl von Frisch began working to uncover the then-shrouded mystery of the language of bees and how bees communicate. With his , he was able to prove that honeybees used a complex set of cues to inform each other about food sources. The most frequently observed of such cues was a dance-like movement performed by forager bees, a movement later coined by scientists as the “waggle dance.”

Austrian zoologist Karl von Frisch was born in Vienna, he was the youngest of four sons Anton Ritter von Frisch, a surgeon and urologist, and his wife Mary (nee Exner). The relatives, who included scientists, doctors and professors, stimulate intellectual development of an inquisitive boy. The country house on the lake. Wolfgang Bryunvinkle, where the family spent the summer, little Charles could no interference to indulge their hobbies, spending long hours in the animal observations. He kept a detailed record of their observations and wrote articles for journals published by nature lovers.
